The first area AA1 may include an active area AA and anon-active area NAA around the active area AA. The non-active area NAAmay surround the active area AA.

The active area AA overlaps the display area DA, and the non-active areaNAA may overlap the non-display area NDA. The second area AA2 and thebending area BA may be referred to as the non-active area NAA.

The sensing electrodes SNE may be disposed in the active area AA, andthe second and third pads PD2 and PD3 may be disposed in the second areaAA2. The sensing lines SNL1 and SNL2 may be connected to the sensingelectrodes SNE and extend to the second area AA2 via the bending areaBA. The sensing lines SNL1 and SNL2 may be connected to the second andthird pads PD2 and PD3. For example, the sensing lines SNL1 and SNL2 maybe connected to the second and third pads PD2 and PD3 via the DEMUXcircuits DMX.

The second and third pads PD2 and PD3 may be respectively connected tosecond and third connection pads PCB-PD2 and PCB-PD3 shown in FIG. 4.The input sensing controller IS-IC may control the operation of theinput sensing part ISP.

The sensing electrodes SNE may have unique coordinate information. Thesensing electrodes SNE may be arranged in a matrix shape to be connectedto the sensing lines SNL1 and SNL2. However, the arrangement of thesensing electrodes SNE is not particularly limited.

The sensing electrodes SNE may be arranged in a plurality of columns.The columns may correspond to a first direction DR1. The sizes of thesensing electrodes SNE disposed in an h-th column may decrease from topto bottom, but the sizes of the sensing electrodes SNE are not limitedthereto.

The input sensing part ISP according to an embodiment of the inventiveconcept may be driven in a self sensing mode to acquire coordinateinformation in a self capacitance manner. For example, the input sensingcontroller IS-IC may operate each of the sensing electrodes SNE as adriving electrode or a sensing electrode. The input sensing controllerIS-IC may apply a driving signal to each of the sensing electrodes SNEthrough the sensing lines SNL1 and SNL2, and receive a sensing signalfrom each of the sensing electrodes SNE.

The sensing lines SNL1 and SNL2 may include a plurality of first sensinglines SNL1 and a plurality of second sensing lines SNL2. The firstsensing lines SNL1 may be respectively connected to the sensingelectrodes SNE to extend in the first direction DR1.

The first sensing lines SNL1 may be connected to one side of each of thesensing electrodes SNE. For example, the first sensing lines SNL1 may berespectively connected to the right side of each of the sensingelectrodes SNE on a plane in FIG. 8 to extend in the first directionDR1. However, the inventive concept is not limited thereto and the firstsensing lines SNL1 may be connected to the left sides of each of thesensing electrodes SNE. In addition, the first sensing lines SNL1 may bealternately connected to the left and right sides of the sensingelectrodes SNE in a column.

The first sensing lines SNL1 connected to the sensing electrodes SNEdisposed in the h-th column are disposed between the sensing electrodesSNE in the h-th column and sensing electrodes SNE in an (h+1)-th columnto extend in the first direction DR1. Here, h is a natural number.

The first sensing lines SNL1 may extend to the non-active area NAA. Thefirst sensing lines SNL1 may extend to the second area AA2 via thebending area BA.

The second sensing lines SNL2 may be disposed in the second area AA2.The number of the second sensing lines SNL2 may be smaller than that ofthe first sensing lines SNL1.

The DEMUX circuits DMX may be disposed in the second area AA2. The DEMUXcircuits DMX may be adjacent to the bending area BA. The bending area BAmay be located between the DEMUX circuits DMX and a 1-1 side S1-1 toextend in a second direction DR2. The 1-1 side may correspond to a lowerside of the active area AA.

The DEMUX circuits DMX may be disposed between the first sensing linesSNL1 and the second sensing lines SNL2. The first sensing lines SNL1 andthe second sensing lines SNL2 may be connected to the DEMUX circuitsDMX.

Each of the DEMUX circuits DMX may be connected to the sensingelectrodes SNE arranged in at least two columns COLs. For example, eachof the DEMUX circuits DMX may be connected to the first sensing linesSNL1 connected to the sensing electrodes SNE arranged in at least twocolumns COLs. Each of the DEMUX circuits DMX may be connected to atleast two second sensing lines SNL2.

For example, the sensing electrodes SNE arranged in two columns COLs andthe two second sensing lines SNL2 are connected to each of the DEMUXcircuits DMX, but the numbers of the sensing electrodes SNE and thesecond sensing lines SNL2 to be connected to each of the DEMUX circuitsDMX may be greater than that.

The number of the second sensing lines SNL2 connected to each of theDEMUX circuits DMX may be smaller than that of the first sensing linesSNL1 connected to the DEMUX circuits DMX. Each of the DEMUX circuits DMXmay connect, two second sensing lines SNL2 to, at least two firstsensing lines SNL1 among the first sensing lines SNL1 connected to thesensing electrodes arranged in at least two columns COLs. Such astructure of the DEMUX circuits DMX will be described below withreference to FIG. 17.

The second sensing lines SNL2 may be connected to the second and thirdpads PD2 and PD3. Similarly to the display panel DP, a first pad areaPDA1, a second pad area PDA2, and a third pad area PDA3 may be providedin a portion of the second area AA2, the portion being adjacent to thelower end of the second area AA2 of the input sensing part ISP. Thesecond pads PD2 may be disposed in the second pad area PDA2, and thethird pads PD3 may be disposed in the third pad area PDA3.

Dotted lines indicating the active area AA in FIG. 8 are it to beseparated from the edges of the outermost sensing electrodes SNE withoutbeing overlapped therewith to more clearly illustrate the active areaAA. However, the edge of the active area AA may overlap the edges of theoutermost sensing electrodes SNE.

The active AA may have a greater area than the display area DA. Theedges of the active area AA may be disposed at the outer edges of thedisplay area DA. The active area AA may be separated from the displayarea DA by different distances. Accordingly, an upper side of the activearea AA may be further separated from the edge of the display area DAthan a lower side of the active area AA.

For example, both sides of the active area AA, which are opposite in thefirst direction DR1, may be referred to as a 1-1 side S1-1 and a 1-2side S1-2. Both sides of the active area AA, which are opposite in thesecond direction DR2, may be referred to as a 1-3 side S1-3 and a 1-4side S1-4. The display area DA may be surrounded by the 1-1 side S1-1,the 1-2 side S1-2, the 1-3 side S1-3 and the 1-4 side S1-4. The 1-1 sideS1-1, the 1-2 side S1-2, the 1-3 side S1-3 and the 1-4 side S1-4 may bereferred to as first, second, third and fourth sides of the active areaAA, or fifth, sixth, seventh and eighth sides of the active area AA.

Both sides of the display area DA, which are opposite in the firstdirection DR1, may be referred to as a 2-1 side S2-1 and a 2-2 sideS2-2. Both sides of the display area DA, which are opposite in thesecond direction DR2, may be referred to as a 2-3 side S2-3 and a 2-4side S2-4. The 2-1 side S2-1, the 2-2 side S2-2, the 2-3 side S2-3 andthe 2-4 side S2-4 may be referred to as first, second, third and fourthsides of the display area DA, or fifth, sixth, seventh and eighth sidesof the display area DA

The 1-1 side S1-1 and the 2-1 side S2-1 may be adjacent to the bendingarea BA. The 1-1 side S1-1 may be closer to the bending area BA than the2-1 side S2-1. The 1-1 side S1-1 may be adjacent to the 2-1 side S2-1,and the 1-2 side S1-2 may be adjacent to the 2-2 side S2-2. The 1-3 sideS1-3 may be adjacent to the 2-3 side S2-3, and the 1-4 side S1-4 may beadjacent to the 2-4 side S2-4.

The distance between the 1-1 side S1-1 and the 2-1 side S2-1 may be afirst distance DT1, and the distance between the 1-2 side S1-2 and the2-2 side S2-2 may be a second distance DT2. The distance between the 1-3side S1-3 and the 2-3 side S2-3 may be a third distance DT3, and thedistance between the 1-4 side S1-4 and the 2-4 side S2-4 may be a fourthdistance DT4.

The first distance DT1 may be smaller than the second distance DT2. Inaddition, the first distance DT1 may be smaller than the third distanceDT3 and the fourth distance DT4. The second distance DT2 may be largerthan the third distance DT3 and the fourth distance DT4. The thirddistance DT3 may be the same as the fourth distance DT4, but is notlimited thereto. The third distance DT3 may also be different from thefourth distance DT4.

According to the aforementioned structures of the active area AA and thedisplay area DA, the edges of the sensing electrodes SNE, which areadjacent to the 1-2 side S1-2, may be disposed farther from a nearestside of the display area DA than the edges of the sensing electrodesSNE, which are adjacent to the 1-1 side S1-1. In other words, a largerportion of the sensing electrodes SNE which are adjacent to the 1-2 sideS1-2 may be exposed compared to the sensing electrodes SNE which areadjacent to the 1-1 side S1-1.

The edges of the sensing electrodes SNE, which are adjacent to the 1-3side S1-3, and the edges of the sensing electrodes SNE, which areadjacent to the 1-4 side S1-4 may be disposed farther from respectivenearest sides of the display area DA than the edges of the sensingelectrodes SNE, which are adjacent to the 1-1 side S1-1.

The edges of the sensing electrodes SNE, which are adjacent to the 1-2side S1-2, may be disposed farther from a nearest side of the displayarea DA than the edges of the sensing electrodes SNE, Which are adjacentto the 1-3 side S1-3 and the edges of the sensing electrodes SNE, whichare adjacent to the 1-4 side S1-4.

The active area AA is shifted and disposed upwards relative to thedisplay area DA, and thus, the non-active area NAA below the active areaAA may be further secured. In other words, the non-active area NAAaround the 1-1 side S1-1 of the active area AA may be further extended.In other words, the non-active area NAA around to the 1-1 side S1-1 ofthe active area AA may increase in size. The non-active area NAA aroundthe 1-1 side S1-1 may include the non-active area NAA adjacent to the1-1 side S1-1, the bending area BA, and the second area AA2.

The first and second sensing lines SNL1 and SNL2 may be disposed in thenon-active area NAA around the 1-1 side S1-1. Since the non-active areaNAA around the 1-1 side S1-1 extends, an area in which the first andsecond sensing lines SNL1 and SNL2 are to be disposed may be furthersecured.

The print layer PIT may be separated from the active area AA to overlapthe non-active area NAA. The print layer PIT may surround the activearea AA. The print layer PIT may be disposed away from the boundary ofthe display area DA. However, when the print layer PIT is disposed intothe display area DA due to a process error, an image may be blocked bythe print layer PIT.

Accordingly, to prevent such a defect, the print layer PIT may bedisposed farther away from an outer side of the display area DA inconsideration of an align margin. In this case, the print layer PIT maybe separated from the active area AA and be disposed away an outer sideof the active area AA.

Referring to FIGS. 8, 9 and 10, the dummy patterns DMY may be disposedbetween the boundary of the active area AA and the print layer PIT. Thedummy patterns DMY may be implemented with slit patterns. For example,the dummy patterns DMY may extend from the non-active area NAA in thesecond direction DR2 and may be arranged in the first direction DR1. Thedummy patterns DMY may be disposed between the first sensing lines SNL1in the non-active area NAA adjacent to the 1-1 side S1-1.

The circuit patterns (for example, the elements of the scan driver SDVand the light emission driver EDV) of the display panel DP may not bevisually recognized from the outside due to the print layer PIT.Configurations are required for blocking circuit patterns of the displaypanel DP in an area between the display area DA and the print layer PIT.

The sensing electrodes SNE disposed outside the display area DA mayblock the circuit patterns so that the circuit patterns are not visuallyrecognized from the outside. The sensing electrodes SNE may not bedisposed between the print layer PIT and the boundary of the active areaAA. Between the print layer PIT and the boundary of the active area AA,the dummy patterns DMY may block the circuit patterns so that thecircuit patterns are not visually recognized from the outside.

When the dummy patterns DMY are not provided in a slit shape but in abox electrode shape, a parasite capacitance produced by the boxelectrode and the circuit patterns of the display panel DP may increase.Accordingly, the dummy patterns DMY may be provided in the slit shape.

Shield patterns SHP may respectively abut on the DEMUX circuits DMX.When viewed on a plane, the shield patterns SHP may overlap the secondsensing lines SNL2 adjacent to the DEMUX circuits DMX. The function ofthe shield patterns SHP will be described in detail below.

An embodiment of the inventive concept provides a display device DDincluding: a display panel DP that includes a display area DA and aplurality of pixels PX disposed in the display area DA; and an inputsensing part ISP disposed on the display panel DP, wherein the inputsensing part ISP includes an active area AA and a plurality of sensingelectrodes SNE disposed in the active area AA, wherein a first distanceDT1 between a 1-1 side (S1-1) of the active area and a 2-1 side (S2-1)of the display area is smaller than a second distance DT2 between a 1-2side (S1-2) of the active area and a 2-2 side (S2-2) of the displayarea, wherein the 1-1 side (S1-1) and the 2-1 side (S2-1 are adjacent toeach other and the 1-2 side (S1-2) and the 2-2 side (S2-2) are adjacentto each other, and the 1-1 side (S1-1) and the 1-2 side (S1-2) areopposite to each other in a first direction DR1, and the 2-1 side (S2-1)and the 2-2 side (S2-2) are opposite to each other in the firstdirection DR1.

The dummy areas DMA may be disposed between the group light emittingareas GPA. The first, second and third light emitting areas PA1, PA2,and PA3 may not be disposed in the dummy areas DMA.

The first and second branch units BP1 and BP2 may be disposed in thenon-light emitting area NPA. Accordingly, light generated from thefirst, second, and third light emitting areas PA1, PA2, and PA3 may benormally output without being influenced by the first and second branchunits BP1 and BP2.

Referring to FIGS. 8 and 11, widths S-W1 and S-W2 of the sensingelectrodes SNE may be set to include a prescribed number of the first,second and third light emitting areas PA1, PA2 and PA3 in the first andsecond directions DR1 and DR2.

Accordingly, as shown in FIG. 8, some of the sensing electrodesSNE disposed in the outermost side may be disposed outside the displayarea DA. The structure of such sensing electrodes SNE is illustrated inFIG. 12.

Referring to FIG. 12, a portion of the sensing electrodes SNE disposedin an outer side of the display area DA in which the first, second, andthird light emitting areas PA1, PA2, and PA3 are not provided may have amesh shape. In other words, the portion of the sensing electrodes SNEdisposed in the outer side of the display area DA may also include aplurality of first branch units BP1 and a plurality of second branchunits BP2 with the mesh shape.

When the portion of the sensing electrodes SNE disposed in the outerside of the display area DA is provided with a box electrode, a parasitecapacitance provided by the box electrode and the circuit patterns ofthe display panel DP may increase.

FIG. 18 additionally illustrates a disposition area of a secondelectrode in FIG. 8.

Hereinafter, a description will be provided with reference to FIG. 5 asnecessary. For example, in FIG. 18, the print layer PIT is omitted inorder to more clearly illustrate the second electrode CE. However, theprint layer PIT shown in FIG. 8 may be provided together with the secondelectrode CE shown in FIG. 18. In FIG. 8, the second electrode CE isomitted in order to clearly illustrate the print layer PIT. When viewedon a plane, the print layer PIT illustrated in FIG. 8 may overlap thesecond electrode CE illustrated in FIG. 18 in the non-active area NAA.

With reference to FIGS. 5 and 18, the second electrode CE may be a boxelectrode commonly disposed with respect to the pixels PX. The secondelectrode CE may extend to the outer side of the display area DA. Thesecond electrode CE may extend to the outer side of the active area AA.The second electrode CE may extend to a portion of the non-active areaNAA. The second electrode CE may be adjacent to the bending area BA. Thesecond electrode CE may prevent or reduce signal interference betweenthe display panel DP and the input sensing part ISP. A function of thesecond electrode CE extending to the outer side of the display area DAand the active area AA will be described in detail below.

FIG. 19 is a cross-sectional view along line III-III′ shown in FIG. 18.

Hereinafter, a description will be provided with reference to FIG. 18 asnecessary.

Referring to FIGS. 18 and 19, a pixel PX is disposed on the substrateSUB, and the sensing electrode SNE may be disposed on the pixel PX. Thedisplay area DA may be demarcated up to an area in which the outermostlight emitting area PA is disposed, and the active area AA may bedemarcated up to an area in which the outermost sensing electrode SNE isdisposed. According to such a structure, the 1-1 side S1-1 may beseparated by the first distance all from the 2-1 side S2-1. A portion ofthe outermost sensing electrode SNE may be included in the area betweenthe 1-1 side S1-1 and the 2-1 side S2-1.

The cross-sectional structure of the display panel DP and thecross-sectional structure of the input sensing part ISP are specificallydescribed above, and thus descriptions thereabout will be omitted.

The line patterns LIN may form the first and secondcontrol lines CSL1 and CSL2 and the data lines DL1 to DLn illustrated inFIG. 4. The transistor TR may be connected to the line patterns LIN.

The second electrode CE of the light emitting element OLED may extend tothe non-display area NDA to be disposed on the fifth insulation layerINS5. The second electrode CE may extend to the non-active area NAA.

The dummy patterns DMY may be disposed betweenthe first sensing lines SNL1 on the second electrode CE.

When the pixel PX is driven, signals may be applied to the transistor TRthrough the line patterns LIN.
